Patent CA-2326397-A1 (CA)
Title: Targeted advertisement using television delivery systems
Inventor: HENDRICKS JOHN S
IPC: H04N21/25
Filed: 1999-04-01
Abstract: A novel multiple channel architecture (265) is designed to allow targeted advertising directed to television terminals (220) connected to an operations center (202) or a cable headend (208). Program channels carry television programs. The invention uses upstream data reception hardware (262, 275, 297), databases (301) and processing hardware (285, 293) and software to accomplish these functions. During commercial breaks in the television programs, advertisements, which are also broadcast on the program channel, are displayed. However, additional feeder channels carry alternate advertising that may be better suited for certain viewing audiences. The operations center (202) or the cable headend (208) generate a group assignment plan (293, 299) that assigns the television terminals (220) to groups, based on factors such as area of dominant influence and household income. A switching plan (291) is then generated that instructs the television terminals (220) to remain with the program channel or to switch to one of the alternate feeder channels during the program breaks. The television terminals (220) record which channels were viewed during the program breaks, and report this information to the cable headend (208) and the operations center (202). The reported information is used to generate billing for commercial advertisers, and to analyze viewer watching habits.

Title: Transformed cell lines which express heterologous g-protein-coupled receptors
Inventor: KESSMANN HELMUT
IPC: G01N33/50
Filed: 1999-06-04
Abstract: According to the invention, transformed cell lines, for example of Ustilago maydis, are used for detecting interactions between GPC-receptors (receptors  with seven transmembrane sites, which interact with guanyl nucleotide-bindin g, regulatory proteins) or GPC-receptor-controlled signal transmission systems and test substances (ligands, modulators), or for searching for substances which are capable of interacting with receptors or signal transmission syste ms of this type. The transformed cell lines have a GPC-receptor-controlled sign al transduction path with positive feedback and are transformed in such a way that they express a heterologous GPC- receptor. The transformed cell lines also contain a reporter gene, the expression of which can be detected using measuring techniques and which is controlled by a promotor. Said promoter ca n be induced by stimulating a GPC-receptor, and is endogenous. The reporter ge ne is endogenous or heterologous.

Inventor: DOLCI GIOVANNI
IPC: A61Q11/00
Filed: 1999-07-16
Abstract: Biocompatible nanocrystalline materials based on apatite with high specific surface properties, having average size of the crystallites comprised betwee n 0.5 and 200 nm and possible lattice deformations and/or defects, are propose d for use in the fields of dentistry and dental hygiene, in particular for the  production of preparations, solutions, toothpastes and materials for the remineralisation of enamel and dentine and for the treatment of dentine hypersensitivity. The apatite-based nanostructured materials appear to posse ss specific physico-chemical properties connected to their nanocrystalline and defective nature, such as the remarkable surface chemical reactivity and the  hygroscopicity, which allow the material to recrystallise as a result of the  metastable character of the nanocrystalline system, to be used for the remineralisation of enamel and dentine. In addition, they possess the most suitable grain sizes to easily and deeply penetrate mechanically within the dentinal tubules, and also cause it to cement the internal surface thereof, both by swelling and by readily reacting with the natural tissues.

Title: Expandable gastroretentive therapy system having a prolonged gastric residence time
Inventor: KRUMME MARKUS
IPC: A61K9/00
Filed: 1999-10-23
Abstract: The invention relates to a device for delaying the pylorus passage of orally administered medicament forms. Said device comprises a component which expands upon contact with the gastric juice and a polymer coat which is permeable to liquids but not to gases. The device can contain an active substance whose release into the gastric juice is mainly controlled by the medicament form into which it is incorporated. Unlike conventional medicament forms with delayed pylorus passage, the release of the active substance does not so much depend on the kind and structure of the polymer coat but is mainly determined by the incorporated medicament form. The inventive device can be easily rolled or folded and can be filled into capsules.

Title: Optimal load-based wireless session context transfer
Inventor: AMALFITANO CARLO
IPC: H04L12/56
Filed: 2001-07-26
Abstract: In a wireless communication network, a system and method for transferring a wireless session context allows a subscriber access unit to transfer the session context from one base station to another base station depending on a loading factor which indicates the throughput load through each of the base stations. A  subscriber access unit which is located in an overlapping wireless coverage area served by both base stations can transfer the session context such that it is served by the base station having the least throughput load. Subscriber access units in overlapping coverage areas will therefore tend to transfer session context to the least burdened base station processor. In this manner, performance is improved because subscriber access units within a wireless coverage area of multiple base station processors are transferred to the base station able to provide the maximum throughput. Further, subscriber access units may be mobile, traveling between coverage areas and passing through overlapping coverage areas. A check is made to determine which of the base station processors corresponding to the coverage areas is least burdened by throughput. A loading factor indicative of resource utilization of each of the base station processors is computed. Each of the loading factors is compared, and the session context is transferred, or switched to the base station having the lowest loading factor.

Patent CA-2363761-A1 (CA)
Inventor: GRUBB KENNETH L
IPC: H01M10/0587
Filed: 2001-11-23
Abstract: The present invention provides a means for attaching a thin terminal extension to a glass sealed terminal electrode utilizing the least amount of space and total height. The terminal extension is of sufficient width to allow a hole sized to the diameter of the pin and the pin is received in the opening in the terminal extension. A series of spot welds are made along the perimeter of the pin at the interface with the terminal extension. If necessary, an insulator is placed between the terminal extension and the surface of the battery case to prevent electrical shorting to the case. Hence, the total height of the assembly is the sum of the thickness of the insulator plus the terminal extension. This design can apply to terminations made externally to or internally in the electrochemical cell.
